State and explain where the "The Chimney-Sweeper" is set?

Blake's "The Chimney Sweeper" is set in London, England in the late 1700s. It describes, from the point of view of a young, innocent chimney sweeper, the cruel life of young boys from the poorest sections of society who were forced to clean chimneys. Young and very slim boys were needed for this work, because only they could fit down the narrow chimneys.

The poem describes the harsh life of these boys who lived in a time before labor laws protected young children from being exploited. As the chimney sweeper recounts, the chimney sweepers have their heads shaved and must rise before the sun is up in the cold to gather up their brushes and bags to head off for work. The chimney sweeper dreams of the childhood an ordinary boy might have, "leaping" and "laughing" as he and his friends run into a river to wash. But such a simple event is simply a dream for this poor child and his fellow workers.
